DOUGLAS Ross has repeatedly refused to say if he would vote to send Boris Johnson to the privileges committee for an investigation into whether he misled Parliament.

The Scottish Tory leader was speaking to the press after a disastrous FMQs where Nicola Sturgeon branded him “ridiculous” for supporting the Prime Minister.

Ross had originally called for the PM to resign if he was found to have broken the rules – but later U-turned despite the fixed penalty notice given to Johnson and cited the Ukraine crisis as his reason for backing him.

The Prime Minister is in India on an official visit as MPs in the House of Commons are debating a Labour-led motion calling for a parliamentary investigation into whether he lied to the chamber.

The debate is set to go on until 5pm on Thursday, with Tory MPs given a free vote on whether to refer the PM for the probe.

The UK Government has withdrawn a counter motion which would have deferred a vote on whether to send Boris Johnson to the committee until after the Sue Gray report is published.

SNP shadow Commons leader Pete Wishart described the move as a "supreme effort of kicking the can down the road".

After a heated FMQs in Holyrood Ross spoke to reporters outside of the chamber. The National asked if he was “dodging Westminster” and the debate by being in Holyrood.

Ross replied: “It’s physically impossible to get from the Holyrood chamber finishing FMQs at 12.45pm to get down to London for a vote at 5pm and I’m not even certain there will be a vote.

“The Government have removed their amendment or not pushed their amendment and it may be pushed through without any division at all.

“I've also been very clear that it’s good we’ll have the privileges committee looking into this, getting all the information into the public domain and answering the questions that still remain on this issue.”

He also said that he hadn’t been in Westminster on a Thursday “for a couple of years” and said it would be “unusual” if he was.

Ross was then asked three times how he would vote if he had been able to make it to Westminster.

At first he said: “Again the situation from last night is different than this morning, I welcome the fact that the amendment has not been put forward and it looks like this will go to the privileges committee so a group of members of parliament can look at this, can look at the evidence and can seek answers for the questions that remained over this issue.”

Asked a second time Ross said “there may not even be a vote”.

When The National pointed out he still hadn’t answered the question and asked a third time he said: “I think it’s important, I can’t say how I would vote if there wouldn’t even be a division.

“This is how the Westminster parliament works if there is no amendment and it goes through without division then there is no vote at all.”

The Prime Minister has so far avoided discussing the vote with the press pool accompanying him to India.
